Cross-boundary e-government systems: Determinants of performance

This study examines the performance of a cross-boundary e-government system. It draws from studies in the fields of e-government, collaborative public management, and information system success with a focus on inter-organizational information systems to develop a conceptual framework. This framework includes efficiency, effectiveness, and accountability as key performance measures; identifies technical, managerial, and inter-organizational factors for success; and develops hypotheses accordingly. Empirical investigation utilizes user-level data from an inter-organizational e-government system that provides integrated commerce and industry service. The results underscore the importance of management support, shared goals, and inter-agency trust in improving all three measures of performance. In addition, citizen-centric and innovative organizational culture enhances efficiency and accountability while administrative interdependence impacts effectiveness and accountability. The managerial and theoretical implications of these findings and future research opportunities are also explored.     

An empirical investigation of students' behavioural intentions to use the online learning course websites

With the development of the Internet in the era of knowledge‐driven economy, e‐learning is experiencing rapid growth. The online learning course websites are drawing more attention as well. This research combines the innovation diffusion theory and the technology acceptance model, and adds two research variables, perceived system quality and computer self‐efficacy to propose a new hybrid technology acceptance model to study students' behavioural intentions to use the online learning course websites. This research finds that compatibility, perceived usefulness, perceived ease of use, perceived system quality and computer self‐efficacy were critical factors for students' behavioural intentions to use the online learning course websites. By explaining students' behavioural intentions from a user's perspective, the findings of this research help to develop more user‐friendly websites and also provide insight into the best way to promote new e‐learning tools for students.

《文心雕龙》中的作品有机论

作品有机构成论是中外文论中的重要内容,中国古代文论中的作品有机构成理论更是独具特色。刘勰在其《文心雕龙》中把文学作品比作人体构成,认为文学作品自身形成一个如人体一般的有机体,即它在内容上是统一完善的,在形式上是完整和谐的。这一比喻不仅能深刻地揭示出文学作品所具有的特点,而且显示了中国古代文论中的人学资源,对于发展和建设中国特色的文艺学具有重要的借鉴意义。     

Tandem Biocatalysis by CotA-TJ102@UIO-66-NH2 and Novozym 435 for Highly Selective Transformation of HMF into FDCA

2,5-Furandicarboxylic acid(FDCA) is a potential biorenewable chemical for applications including plastics, polyamides, drugs, etc. The selective biosynthesis of FDCA from 5-hydroxymethylfurfural(HMF) by a specific enzyme poses a great challenge. In this study, we reported an efficient strategy to produce FDCA from HMF by the tandem biocatalysis of laccase(Cot A-TJ102@UIO-66-NH_2) and Novozym 435. For the first step, a nanoparticle metal–organic framework was synthesized as a carrier to immobilize Cot A-TJ102@UIO-66-NH_2, which was assigned for the production of 5-formyl-2-furancarboxylic acid(FFCA) and featured an enzyme loading of 255.54 mg/g, specific activity of 135.90 U/mg, and solid loading ratio of 99.65%. Under optimal conditions, an ideal FFCA yield of 98.5% was achieved, and the Cot A-TJ102@UIO-66-NH_2 presented a high recycling capacity after 10 cycles. For the second step, Novozym 435 was applied for the further conversion of FFCA into FDCA, presenting a high FDCA yield of 95.5% under the optimized conditions. Novozym 435 also exhibited a high recyclability after eight cycles. As a result, the tandem biocatalysis strategy provided a 94.2% FDCA yield from HMF, indicating its excellence as a method for FDCA production.
